Answer 3

To solve the equations, we need to find the value of the variable "у" in the first equation and the value of the variable "п" in the second equation. Let's solve them step by step:

1. 7×у + 9 = 51

To isolate "у," we'll first move the constant term (9) to the other side of the equation:

7×у = 51 - 9 7×у = 42

Now, to find the value of "у," divide both sides by 7:

у = 42 ÷ 7 у = 6

So, "у" is equal to 6.

2. 26 + (72 ÷ п) = 35

To isolate "п," we'll first move the constant term (26) to the other side of the equation:

72 ÷ п = 35 - 26 72 ÷ п = 9

Now, to find the value of "п," divide both sides by 72:

п = 72 ÷ 9 п = 8

So, "п" is equal to 8.

Therefore, the solutions to the equations are: у = 6 п = 8
